Specification of Letters Patent.

Patented Mar. 20, 1917.

Application filed July 23, 1915. Serial No. 41,572.

To all whom it may concern:

Be it known that I, JOHN WV. GRAHAM, a citizen of the United States,residing at Hinton, in the county of Summers and State of lVestVirginia, have invented certain new and useful Improvements in'lypographical or Slug-Casting Machines, of which the following is aspecification.

My invention relates to typographical machines, such as linotypes of theoriginal construction, wherein circulating matrices are released from amagazine in the order in which their characters are to appear in print,and then assembled in line together with expanding spacers, the composedline brought in contact with the face of a mold, the mold filled withmolten metal to form a line of type or slug against the face of; thematrices, which produce the type char acters thereon, and the matricesthereafter returned to the magazine from which they were originallydrawn.

More particularly it relates to that class of machines having a serlesof magazines,

any one of which can be brought into operative position and lockedtherein, and wherein the magazines are removable and interchangeable.

My invention is embodied in the construction of the arms which guide thetravel of the magazines, and in the construction of the locking device,but I do not claim the principle involved either in the housing of themagazines, the arms, or the mechanism which guides the travel of the'magazines upward or downward, to be part of this invention, as they areclaimed in previous applications filed by me. The main feature of thisinvention, is embodied in the feature series of magazines when broughtto the lowest point of operative position, which brings the uppermostmagazine into operative position, are then suspended in slotted arms.The guide rollers on the lower rack rest in the bottoms of the slots inthe arms and the racks and magazines are thus suspended. A supportingbase can now be lowered away from the racks and magazines, and themagazines and racks are so made as to be heavier behind than in front.As the base moves downward the racks and magazines can be brought to asubstantially horizontal position to facilitate the quick and easyremoval of the magazines.

In the accompanying drawings I have shown my invention as an example andin a preferred way, and many changes and variations may be made thereinwithout departing from the spirit or principle of this invention, and Iwish to be understood that I do not limit myself to any form, orembodiment, except in so far as such limitations are specified in theclaims.

Referring to the drawings, Figure 1 is a side view of-a portion of alinotype machine having my invention applied thereto. 2 is a rear viewof the forked arm A. Figs. 3 and 3 show top and side views of a rack andits magazine. Figs. 4 and 4* show front and side views of the automaticlock.

Referring to Fig. l

A is the main forked arm of the machine.

A is an arm extending back from the main arm A at each side to supportthe distributing mechanism.

A is a brace at each side connecting the frame of the machine with thetop of the arms A. e

A shows the slots in the arms A.

A shows the holes in the arm A arranged in different vertical planes asshown to engage the lock pins.

B is the base which supports the magazmes.

B are the rollers in the base which allow the lowermost rack to moveendwise on the said base.

B shows the threaded nuts which engage the screws B CC and 5 are rackswhichsupport the magazines.

C shows the guide rollers on the racks.

C shows. the supporting rollers on the racks.

3 shows the stop dog in the saidracks to hold the magazines in place(see Fig. 3).

D shows the lock pins (see Fig. t)

D is the diskv which'supports the heads of the lock pins. (see Fig. l).

D is the shaft which operates ing device.

D are universal joints in the shaft D D shows a dial.

D shows a hand wheel having on it a finger D7.

E shows a hand wheel to raise and lower the magazines.

E? shows the, shaft to operate the; lowers d, rai i g mechanism.-

the lock- E shows the cross shaft connecting the two screws B.

M shows a magazine.

M shows the extended ends of the strengthening bars on the magazine M,which work in conjunction with the stop dogs C to hold the magazine inplace.

In operating the machine the hand wheel E is turned to the right or leftas desired, and operates the shaft E by intermeshed bevel gears. Theshaft E is connected to the screws B by inter-meshed bevel gears, andthe said screws are engaged with the nuts B on the base B, thus raisingor lowering the magazines. To bring the magazines to a horizontalposition, in order to remove a magazine or for any desired purpose, thebase B is lowered until the guide rollers C of the lowermost magazinerest on the bottom of the slots A in the arms A. The base is thenlowered sufiiciently to allow the magazines to tilt backward to thedesired angle. The magazines as ordinarily constructed are heavier attheir rear than at their frontal ends, and thus will tilt downward atthe back by gravity. The arms A are made slotted to receive the guiderollers on the racks, and the said slots are made vertical above theoperative position. Below the operative position the slot runs back atan angle sufiicient to allow the lowermost magazine, when resting withits guide rollers in the bottom of the slot, to tilt down at the back soas to rest on a line substantially horizontal and still allow itsfrontal end to rise up without interfering with the escapement channel,and so that the other magazines of the series will also come to ahorizontal position and not interfere with the escapement channel.

No power raising or lowering device is shown on this machine, but it isobvious that any such device may be applied, such as any of the devicesshown in the previous applications for patents on similar machines, byme. The entrance channel is hinged on a slidable block and may be movedoutward without changing its upright position, but this feature is nopart of this invention, being claimed in a previous application.

In operating the locking device the hand wheel D is turned to bring thefinger D to the desired number on the dial D The dial 1) is numbered tocorrespond to the number of magazines. The disk D is made circular andthe heads of the lock pins rest upon it. The disk has at a preferredpoint on its rim a depression large enough to receive the head of onepin. The pin whose head is located above the said depression can dropinto its corresponding hole A in the arm A when the base is moved to theproper position, but the other pins resting on the thicker parts of thedisk D are held out and cannot engage their corresponding holes. Thepins are set in the base preferably in the form of a half circle and theholes in the arm A are set staggered across the said arm so as to be inline vertically each with its corresponding pin. The shaft D is madepreferably telescoped so that it can lengthen and shorten as the basemoves up or down, and the said shaft is made with flexible joints. Thelock pins D are pressed in by any desired spring mechanism.

Having described my invention, its construction and operation, what Iclaim and desire to secure by Letters Patent of the United States, is asfollows:
